Hello @SteveSJ
Thank you for reaching out on the community and telling us about your issue. I do apologize for the issue you're having. Are you getting this extra transaction in addition to the payment you're receiving or only one transaction? If you wouldn't mind could you take a screenshot of the transaction and any additional information as well.

Once you get the chance let us know what you're able to find out. From there we'll see what we able to find next.
Thanks,
Quicken Francisco
